本文针对低信噪比地震资料采集监控分析的困难,研究地震资料采集监控分析技术,从而提高现野外地震资料采集的监控效果。文中对研究讨论了剖面法信噪比估算技术和自相关分析技术,剖面法信噪比估算方法以小时窗作为研究对象,并滑动外推进行整条测线的信噪比计算,对全测线资料信噪比的描述更加直观;自相关分析技术以地震资料的自相关函数作为研究对象,可以对整条测线的激发效果做出较客观的评价。 In view of the difficulty of monitoring and analysis of low S / N seismic data acquisition, this paper studies the monitoring and analysis technology of seismic data acquisition so as to improve the monitoring effect of field seismic data acquisition. In this paper, we discuss the SNR estimation method and the autocorrelation analysis technique in profile method. The SNR estimation method in profile method takes the small window as the object of study and extrapolates the signal to noise ratio of the whole survey line by sliding extrapolation. The description of signal-to-noise ratio of line data is more intuitive. Autocorrelation analysis technology takes the autocorrelation function of seismic data as the research object, which can objectively evaluate the excitation effect of the whole line.
